TYPE-CASTING MACHINE.

Application filed March 23, 1920.

To all whom it may concern:

Be it known that I, KYorA SUs1ivro:ro, subject of Japan, residing at No.13, Toyooka Machi, Mita, Shiba Ku, Tolryo, Japan, have invented new anduseful lmprovements in Type-Casting Machines, of which the following isa specification.

This invention relates to improvements in type casting machines,consisting of a board having a large number of matrices of d fferentcharacters arranged on one of its surfaces, means to move the saidmatrix board, right and left, up and down, and means to make any desiredmatrix tofit to the mold. The object of this invention is to obtain amachine by which types for multiform characters can be cast with greatrapidity.

The accompanying drawings shows an ex ample of a simple machineembodying my invention, in which Figure 1 is a front View, V

Fig. 2 is a vertical section, and

Fig. 3 a plan.

The same reference characters designate the same or corresponding partsthroughout all the figures. v

In type casting machines hitherto generally in use, matrices must bechanged whenever it is desired to cast different characters. Thus, in alanguage such as Japanese which consists of so many characters as manychanges of matrices must be made, which necessitates the loss of muchlabor and time. This invention has been made for the purpose ofpreventing such loss, and the chief improvements lie in the constructionof matrices and their movements with regard to the mold.

At the upper part of a frame 1 is fixed a melting apparatus 2, the upperpart of which forms a type-metal pot and the lower part, a furnace 4C.To the furnace 4 is led a gas pipe 5, which supplies gas to melt metalin the pot 3. A plunger 6 fits a cylindrical chamber 7, its upper partloosely passing through an arm 9 fixed to the melting pot 3. A coiledsprlng 8, the upper end of which bears against the arm 9 and the lowerend against a shoulder formed on the plunger 6, and thereby presses theplunger downward. The upper end of a curved lever 10 which is pivoted at11 to the arm 9, loosely passes through a hole in the plunger 6, and itslower end is provlded with a roller 12. 13 is a mold fixed at the top ofSpecification cf Letters Patent.

a, supporter 14, the lower end of which is firmly fixed to a rod 15mounted for rotation on the frame 1. The supporter let is provided atits middle part with a roller 17 1s a matrix board on the front face ofwinch are represented a plurality of different characters 18 and on theback of which are firmly fixed matrices 18' of these characters atplaces exactly corresponding to their position on the front surface. Thematrix board 17 is slidably mounted on a pair of transverse guide bars21 so that it can be moved to the right or left on the said guide bars,while the guide bars 21 themselves are mounted on a pair vertical guidebars 24. in such a way that they can be moved up or down. Thus thematrix board 17 can be moved, by means of a knob 22 carried by theboard, to the right or left, as well as vertically, to any desiredposition. The vertical guide bars 2 1 are strengthened by cross-pieces25 and 26, and at their lower ends they are mounted for rotation on therod 15. 27 is a main shaft, supported for rotation in the sides of theframe 1. On one end of the main shaft is fixed a fly wheel 28 providedwith a handle, and approximately at the center of its length is mounteda cam 29. A spring 30 fixed at one end to a stay 31 of the frame 1 pullsthe supporter 14: and consequently the roller 16 is pressed against thecam 29. Another spring 32 also fixed to the stay 31 pulls an arm 26 ofthe cross-piece 26 which causes a roller 33 at the end of the arm 26' topress against the cam 29. The plunger 6 which is pressed down by thespring 8 can be made to rise by means of the curved lever 10, its roller12 being pushed away by the cam 29.

Now, if the cam is turned in the direction of the arrow, the rollers 12,16 and 83 will successively be brought to the indented part of the cam.Thus when the roller 83 falls into the indented part of the cam, thespring 32 will pull the arm 26 and thereby the matrix board 17 will bebrought into close contact with the mold 13. Next, the roller 16 willfall into the indented part of the cam, when the spring 30 will pull thesupporter 14, and the mold 13 together with the matrix board 17 will bebrought into close contact with the melting apparatus 2. Lastly, theroller 12 will fall into the said indented part, and the plunger 8 whichhas been raised, the roller 12 of the curved lever 10 being pushed awayby the cam, will fall down and the melted type metal contained in thechamber 7 will be forced into the mold 13. On the cam further moving,the rollers 33, 16 and 12 will be pushed away one after another, and thematrix board 17, the mold 13 and the melting apparatus 2 will beseparated, and the type cast and remaining in the mold can be removed byany suitable mechanical contrivance or by hand.

A pointer 36 which extends from the cross-piece 25 always points to theplace on the front surface of the matrix board, which exactlycorresponds to the mold 13, so that the matrix of any desired charactercan be brought to the front of the mold. In order to further secureexact relative position of a matrix and the mold, vertical andhorizontal racks 87 are fixed to the matrix board and horizontal andvertical bars 88 atached to the supporter 14 to engage the racks.

I claim:

1. In a type casting machine, the combination of a frame, a mold carriedthereby, a matrix board supported on said frame in juxtaposition to saidmold and adjustable horizontally and vertically, said board carrying onthe side adjacent to the mold a plurality of matrices, means foradjusting said board to carry either of said matrices into alinementwith said mold, and means for indicating at the opposite side of saidboard the alining position of said matrices.

2. A type casting machine consisting of matrix board movable up anddown, right and left, on one side of which are arranged matrices of alarge number of characters and on the other side are representedcharacters corresponding to the matrices; a type mold provided facingthe matrices with a small space between; means to bring the matrix boardinto contact with the type mold; and a pointer which points to thecharacter corresponding to the matrix which is in position to fit withthe type mold, substantially as and for the purposes hereinbefore setforth.

3. In a type casting machine, the combination of a frame, mold carriedthereby, a matrix board supported on said frame in juxtaposition to saidmold and adjustable horizontally and vertically, said board carrying onthe side adjacent to the mold a plurality of matrices, means foradjusting said board to carry either of said matrices into alinementwith the mold, and coiiperating means carried by the frame and board forindicating at the opposite side of the board the alining position ofsaid matrices.
